so I should have 168 x 2 + 154 + 140 + 96 which is 726.
Seem to have missed your 4th card. Kvitova +20%.
In the rankings I still have 6 points for that card, but Petra won her 1st round match.
So you would have 96 points for that card instead of 6. That makes indeed a total of 726 points.
She plays today, so I will fix this in the update tonight.
